UPDATE: We've temporarily disabled the opt-in to this feature due to an unexpected issue in Proton Drive for Windows. The team is working on a fix and will re-enable it soon. Proton Mail now supports post-quantum encryption. While quantum computers can’t break today’s encryption yet, preparing early matters. Data encrypted today could be targeted in the future. You can enable post-quantum protection for new encrypted emails, on any plan, including free. Learn more: https://proton.me/blog/introducing-post-quantum-encryption
